Versico TPO and EPDM on Denton and Fort Worth Commercial Roofs: Thickness, Warranty Terms and Hail Coverage

If you own or manage a warehouse, strip center, church or office in Denton or Fort Worth, you’ve probably seen Versico on a bid. It’s one of the big single-ply makers, and it makes both TPO and EPDM. The membrane name matters less than how the system is built, because that decides the warranty term and whether hail is covered at all.

I’m Blake Snow, and I’ve been roofing for 30 years. We install commercial single-ply systems to manufacturer specs, using certified installers. Here’s what Versico’s own documents say.

Who is Versico?

Per Versico’s company brochure and About page:

• 1981: Goodyear starts a roofing division.
• 1993: Carlisle Construction Materials buys Goodyear’s roofing division and sets up Versico Roofing Systems.
• 1998: Versico starts making VersiWeld TPO in Senatobia, Mississippi, on what it calls the industry’s first dedicated TPO line.
• 2022: Versico opens its sixth TPO line, which it says made the industry’s first 16-foot TPO sheet.

Versico is based in Carlisle, Pennsylvania. We’re certified with Carlisle, and Versico is a Carlisle company, but they’re separate brands with their own warranty programs.

Versico’s membranes in plain English

• VersiWeld TPO: a scrim-reinforced, heat-welded thermoplastic sheet in white, gray or tan, at 45, 60 or 80 mils. Special colors come in 60 mil. Seams are heat-welded at least 1½ inches wide.
• VersiWeld QA TPO: a “quick-applied” TPO with a factory pressure-sensitive adhesive on the back, at 60 or 80 mils.
• VersiFleece: fleece-backed TPO, EPDM and PVC sheets for adhered systems, set in adhesive, asphalt or Versico’s RapidLock.
• VersiGard EPDM: black or white rubber membrane, non-reinforced or reinforced.
• VersiFlex PVC and KEE HP: Versico’s PVC-family membranes.

VersiWeld TPO: thickness vs. warranty and hail

From Versico’s System Warranty Availability chart:

The takeaway for a Denton or Fort Worth owner: a mechanically attached TPO roof, which is often the lowest bid, gets no Versico hail coverage at any thickness. If hail coverage matters to you, the membrane has to be adhered over an approved cover board.

VersiGard EPDM: thickness vs. warranty and hail

The cover board rule

Versico’s chart says hail coverage requires an approved, adhered cover board: SecurShield HD or HD Plus, SecurShield HD Composite, DuraFaceR Composite, DuraStorm VSH, DensDeck Prime or DensDeck StormX at least ½ inch thick, or SECUROCK at least ½ inch thick.

That board sits between the insulation and the membrane and takes the hit. When you compare bids, check that the cover board is named, adhered, and on Versico’s list. If a bid promises hail coverage on a mechanically attached roof with no cover board, ask for the warranty sample in writing.

Puncture coverage

Versico also offers an Accidental Puncture Warranty on some systems. It covers labor hours and materials for repairs, with hours capped by system: for example, up to 16 hours on adhered 80-mil VersiWeld TPO and up to 32 hours on adhered 90-mil VersiGard EPDM. Busy roofs with HVAC service traffic are where this pays off.

TPO or EPDM in Denton and Fort Worth?

• TPO: white or light-colored, heat-welded seams, and very common on Texas warehouses, retail and offices. Good when the roof sits in full sun all summer.
• EPDM: a long track record, simple to repair, and available in black or white. Good on roofs with lots of penetrations or where rubber’s flexibility helps.
• PVC or KEE HP: consider these for restaurants or other roofs with grease or chemical exhaust.

We price more than one system when it makes sense and walk you through the trade-offs. See our TPO roofing and EPDM pages, or compare systems in our TPO vs. modified vs. coating guide.

What to check on any Versico bid

1. Thickness and attachment, written out (for example, “80-mil VersiWeld TPO, fully adhered”).
2. Warranty term and wind speed, with the matching Versico chart line.
3. Hail coverage size, and the named cover board.
4. Who issues the warranty. Versico system warranties go through Versico’s authorized contractor network and a Versico inspection. Ask for the warranty sample and who will be on site.
5. Insulation and drainage: tapered insulation, crickets, scuppers and drains, so water doesn’t sit.

Our own commercial jobs carry 10- and 20-year NDL warranty options. Read more on our NDL warranty page.

After a hailstorm

Document the roof before repairs, and call the manufacturer before anyone alters a warrantied roof. In Texas you generally have 1 year from the date of loss to file a claim, but check your policy. Our commercial hail claims page explains the process.

We also do metal

Some buildings are better off in metal. We run our own roll formers for 24- and 26-gauge standing seam and R-panel, and our metal lead time is typically 1 to 2 weeks. See commercial metal roofing.
